What we don’t need to do is help Iran finance the development of nuclear weapons and delivery systems. Unfortunately it might be too late now.
I agree with you but only in part.
AGREE: Iran with nuclear weapons
can be an accident waiting to happen.
HALF AGREE: North Korea has nuclear weapons but are not an immediate threat because they are not being taunted, intimidated and threatened by the US. NK has no natural resources that the West wants to get their grubby hands on. But Iran is being taunted, intimidated, and threatened by the US .... and they have oil, ie. something the West wants to steal just as they did up until the Iranian Islamic Revolution. If the West would make friends with Iran then there might not be anything to worry about.
DISAGREE:
1). The US and GB carried out a political coup in Iran, thus destroying (forever, apparently) Iran's Democratic government. I say
apparently forever because that coup and overthrow of Iran's Democracy has left the Iranians very skeptical about Western-style so-called Democracy.
2). You and I might agree that there really isn't a true Democracy in the US and I can prove it with the statistics but the whole Middle East is convinced that the US really does represent Democracy because it claims that it does and because it has never been punished for its non-Democratic deeds.
3). Since the Islamic Revolution Iran has many times offered its hand in friendship to the US in the wish of creating a better relationship with the West in general. The West has refused to cooperate with Iran. On 9/11 Iran contacted the US and offered its help in tracking down Al Qiada. After all, Iran has its ear to the ground in the region and could be an enormous assistance in that endeavor. The US refused.
4). It seems clear to me that Iran is right in being wary of the West because of everything (and more) that I have just described here. The US isn't interested in peace in the region. The Americans only want to steal Iran's oil just as they did in Irak and just as they did in Iran up until the Islamic Revolution.
5). It all leads me to one conclusion: Iran must be ready and able to defend itself against the worst the US can bring to bear.
Nuclear bombs are a necessity for Iran's existence.
BOTTOM LINE: I agree with your initial concerns but Iran has
NO CHOICE.
